Hiii Mate
=================================
L.H.S = 2(cos⁴60⁰ + sin⁴30⁰)-(tan²60⁰ + cot²45⁰) +3(sec²30⁰)
= 2[(1/2)⁴ + (1/2)⁴ ] -[ (√3)² + 1²] + 3(1)²
= 2 (1/16+1/16) - (3+1) + 3
= 2 (1+1/16) -3+3
=2(2/16)
=4/16
=1/4
=R.H.S
==========================================
Hope it will help u............
Plzz mark as brainliest.....
